VIOLET-RAY VACUUM CUP.

Application filed June 24, 1927; Serial No. 201,057.

ting that portion of the body under reduced pressure. 1

It is an object of this invention to provide a quartz vacuum cup that may be applied to a localized portion'of the body to draw the blood to the surface of such localized portion so that more effective treatment with ultraviolet rays can be obtained.

Other and further important objects of this invention will become apparent from the disclosures in the following description tubing 7 for the purpose of exhausting the,

and appended claims.

In the accompanying drawings which illustrate a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the differ; 3 cut views:

Figure 1 is a top plan view of a violet ray quartz vacuum cup embodying the principles of my invention.

Figure 2 is a sectional ,view of the same taken on line IIII of Figure 1, with parts in elevation.

As shown on the drawings: 7

The reference numeral 1 indicates a dishlike vessel formed of material capable of transmitting ultra-violet rays. Fused quartz .is knownto be especially adapted for this purpose. Said vessel 1 is provided with a rim 2, all points of which lie in substantially the same plane. Said rim 2 is formed with a wedge-shaped recess 3 into which is inserted a gasket 4 of some resilient material such as rubber. An aperture 5 is formed in one end ofthe vessel 1 and a suction bulb 6 is connected thereto by means of a flexible space inclosed by the vessel 1. t

In using the device, the vessel 1 is applied to the particular portion of the patients body to be treated, with the gasket 4 in tight contact with the surface of the body. The

i bulb 6 is then compressed and suflicient air exhausted from the space inclosed between the vessel 1 and the body surface to cause the blood to be drawn to the surface so inclosed. Violet rays l-are then directed toward the vessel 1 and bed therethrough to the body surface covered by said vesel 1. It

benefit is to be derived. that the type of suction applying device is immaterial so long as the particular device Illinois.

has been found that this method of treating the surface of the body with ultra-violet rays is much more effective than the ordinary method, due to the fact that the blood is drawn to the surface and is thereby subjected more directly to the effect of the rays.

It is obvious that the shape of the vessel 1 may be varied to conform. with different parts of the body so that localized treat ments may be applied wherever the greatest It is also apparent employed is capable of partially exhausting the air from the space inclosed by the vac uum cup. An ordinary rubber bulb such as used in syringes serves the purpose satisfactorily.

I am aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention and I, therefore, do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

l. A device of the class described, for use in treating the body with ultra-violet rays, comprising a dished member formed of material capable of transmitting ultra-violet rays and means connected with said member for creating sub-atmospheric pressure therein when said member is applied to the surface of the body.

2. A device of the class described, comprising a quartz dishlike vessel adapted to be applied to the surface of the body to transmit ultra-violet rays thereto and means for partially exhausting the space inclosed between said vessel and the body to draw the blood to the surface inclosed by said vessel.

A device of the class described, comprising a dishlike vessel formed of quartz, a resilient gasket secured to the rim thereof for forming an air-tight joint when the vessel is positioned upon the surface of the body and a suction producing means con-.

nected to said vessel for partially exhausting the space inclosed between the vessel and the body surface.

In testimony whereof I have hereunto subscribed my name at Chicago, Cook county,

EARL H. ODELL.
